We had Henry out to give us a quote on a whole-home dehumidifier and boy was he refreshing! He did an amazing job explaining what we needed and made sure I understood what steps we needed to take in order to get our issues resolved. He has so much more experience than anyone else we had out and was the most intelligent and qualified of all the people we’ve talked to. His honesty, integrity, and kindness was unmatched by any other company. (…and trust me-over the past 6 weeks of struggling to find someone to trust, with multiple companies coming out trying to get us to just get an entirely new system instead of fixing the problem-our system is just 5 years old-I cannot tell you how much that meant to me.) THANK YOU, Henry and McCann Services, for your help!

McCann is a really good hvac company and has been in this business for a very long history. I had Steven to come and make the estimate for a 4 ton 18 seer Daikin fit unit, and he did really good job explaining how each parts worked. I’ve been shopping around for a week and got 8 quotes for that Daikin unit. I have to say, McCann’s price is one of the best. They’re really honest experts with extensive experiences.

I have used McCann Services as my primary home HVAC contractor for over 20 years, when Gene McCann ran the business. Gene retired and his son has taken over but the company continues to give the personal and professional service that Gene did. My go-to technician for most servicing is Ruben, who is always on-time, courteous, professional, and informative. I recommend McCann Services for all HVAC servicing.

I had two Daikin mini-split compressors feeding eight units installed when I renovated my house. Since I only had problems with them and spent thousands of dollars to have them fixed with zillions of incapable companies showing up just trying to rob me one after the next (not counting the crooked initial contractor Patrick Combe who stole my money anywhere he could and left us with a non functioning system). Thanks to Ruben the technician McCann sent over he found the units where not properly installed, the control wires where crossed with the refrigerant lines, totally confusing the control systems. Kudos to Ruben who was very methodical in identifying the source of the problem. Thanks to him we are weathering our hot summer with cool, consistent AC! Ruben, you're a champ! Thank you! Philippe

I used McCann Services today because my AC went out. The technician Robert called me and gave me an estimated arrival time and showed up on time. He did his inspection and found the problem and took the time to explain to me what's wrong and answered all my crazy questions. He replaced the part with confidence and knew what he was doing. I will continue to use this company for all my AC and heating needs.
